16 Claims. {CL 53-179) This invention relates to a wrapping or packagingmachine and method, and one which is particularly desirable for use inwrapping or packaging food. The main objects of this invention are:

First, to provide a wrapping or packaging machine which will rapidlypackage a group of articles such, for example, as poultry giblets, sothat the package may be inserted as such into the cavity of a dressedpoultry carcass.

Second, to provide a wrapping or packaging machine which willeconomically produce a moist wrapped package such, for example, asgiblets, that will not adhere to or absorb moisture from the carcass inwhich it is inserted.

Third, to provide a machine which may have these advantages which may beeasily kept in a sanitary condition.

Fourth, to provide a wrapping or packaging machine which is well adaptedfor packaging products of irregular shape which are substantially sealedwithout the use of adhesive material other than water.

Fifth, to provide a machine of this character in which the packagedarticle may be of a selected group such, for example, as giblets, withthe desired selections in each package.

Other objects and advantages of this invention will be apparent from aconsideration of the following description and claims. The drawings, ofwhich there are four sheets, illustrate a highly practical form of theinvention.

FIG. 5 is a View similar to FIG. 4 showing a package in partially rolledcondition and position.

FIG. 6 is a fragmentary transverse cross sectional view taken along theplane of the line 6-6 in FIG. l.

FIG. 7 is a fragmentary vertical longitudinal cross sectional viewthrough the wrapper folding section of the machine taken along the planeof the line 7-7 of FIG. 2.

FIG. 8 is an elevational view conventionally illustrating the completedpackage formed on the machine.

The embodiment of my invention illustrated is especially designed forthe wrapping or packaging of giblets, but is should be understood thatthe major features thereof are desirable for use in the packaging ofvarious products. The machine illustrated includes a suitable frameworkof generally rectangular section designated generally by the numeral 1.In the machine illustrated, the front end of the machine, as viewed inFIG. l, is at the right and is provided with a support 2 for a roll 3 ofwrapping paper. It will be understood that this paper may be varied inwidth, but for the wrapping of giblets, for example, a web ofapproximately one foot in width is suitable and it is of a type thatdoes not disintegrate when moistened. For wrapping food products, careis taken that the paper is in a sanitary or uncontaminated condition.

The web guide roll 4 is mounted on the support 5 and directs the web ofpaper into the inlet end of the chute 6i. The former 7, supported by across piece or bridge 8 within the chute, forms the incoming web into anupwardly facing trough or channel section. The web is drawn or advancedinto the chute past the forming means 7, by driven feed roll 9 which isin contact with the bottom or bight portion of the trough shaped web.The pressure roll 1d is swingably supported on the arms 11 and holds theweb in supported and feeding engagement with the feed roll and holds theupturned sides of the web in upright position. At the rear of the roll 9the web is picked up and advanced by a conveyor, that consisting of thethree parallel belts 12 trained over the upper rolls 13 and 14 and thelower rolls 15 and 16 which form driving rolls and tightening means forthese conveyor belts.

The roll 15 is driven `by the belt 17 from the transmission 18 of thedrive unit 19. The rolls 13 and 14 are desirably slightly crowned tocenter the belt and are provided with annular ribs 20 and 21 whichmaintain the belts in properly spaced relation. The ribs 21 on the roll14 project above the belts and serve to separate the web from the beltsat the discharge end of this conveyor, as will be described presently.

At the rear or at the left of the roll 9 and projecting over the frontends of the belts 12 is a battle or chute mem-ber 22 which projectsdownwardly over the front of the belts and between the upwardlyprojecting sides of the web to discharge onto the bight portion of theWeb. Supportedly mounted above the belts by the side rails 23 is a feedconveyor 24 of the chain and sprocket type, carried by sprocket shafts25 and 26. The conveyor 24 is provided with a plurality of uniformlyspaced outwardly facing cup-like receptacles adapted to receive theproduct to be packaged such, for example, as fowl giblets.

In the embodiment illustrated, inasmuch as the conveyor 24 is disposedabove the conveyor previously described, the conveyor is operated sothat its pans or receptacles 27 are advanced to the line on the upperreach of the conveyor by means of the `drive belts 28 and 29 between theshaft of the roll 15 and the sprocket shaft 26. The drive for this feedconveyor is arranged to advance and discharge on the pan for everypredetermined number of inches of the paper web which is being advanced`and positioned to receive the disch-arge. This means that the articlesto be packaged are discharged in predetermined spaced relation on theWrapping web.

When used for packaging giblets, for example, the operators standingalong one or both sides of the machine deposit the giblets or otherarticles to be wrapped into the pan in the desired number and selection.To keep the giblets or other articles and scraps thereof dropped by theoperators from falling into the conveyor, a removable catch pan isprovided. This is supported by the lug 31 from the rolls 25 between theend reaches of the conveyor.

The conformed web of paper with the giblets or articles to be packagedthereon is engaged as it is translated by the folders 32 and 33, seeFIG. 2, that fold the opposite or outwardly projecting sides of thetrough shaped web laterally inwardly into overlapping relation. Thewrapper so folded is indicated in somewhat exaggerated condition at Wwith a group of giblets indicated at G.

As stated, the embodiment of our invention illustrated is designed andadapted for the wrapping of giblets and the apparatus is provided withwetting means, preferably in the form of spraying means. In theaccompanying drawing the water supply means is indicated at 34 and thewater heater, if necessary, is indicated at 35. A

pipe 36 from the heater delivers to a jet or spray nozzle 37 that cleanseach inverted pan 27 as it moves along the lower reach of the conveyor24. In order to catch and prevent the drip and debris from the pans fromworking into the folds of the wrapper, an inclined drip pan 38 issupported under the lower reach of the conveyor and over the foldingmembers 32 and 33. A drain hose 39 disposes of the drippings.

A branch 40 of the pipe 36 extends to a nozzle 41 positioned to sprayjust enough water on the surface 'of belts 12 to make them adhere to thedry incoming web of wrapping paper when they meet it at the roll 13.This permits the conveyor belts 12 to advance the web and the articles Gwithout further separate drive on the web of paper. After passing thefolders 32 and 33 the wrapper W and articles G are delivered over theroll 14 to the transfer plate 42, see FIG. 3, having a fixed knife blade43 on its trailing or rear edge. The raised .ribs 21 on the roll 14assure that the wet wrapper is separated from the roll onto the plate 42and does not follow around the roll. A rotating knife blade 44 carriedby the shaft 45 coacts with the blade 43 to sever the wrapper web intoseparate packages. The knife shaft 45 is supported in suitable bearings46 and is driven in properly timed relation to the web W and conveyor 24by the belts or chains 47 to cut the folded wrapper into equally spacedpackages.

The severed and separate packages of articles are delivered from theknife 44 onto a delivery belt 48 trained over the rollers 49 and S0. Theconveyor 48 desirably has a rough surface as indicated and is driven bythe belt 51 and drive roll 52 at a somewhat faster rate than conveyorbelts 12 so that the separate packages P of articles are spaced out onthe belt. The packages P, and particularly the top folds thereo-f, arestill relatively dry and loose so the conveyor 48 carries themimmediately under a hood 53 having one or more spray nozzles 54 mountedtherein and connected to the pipe 34 to spray or discharge downwardlyupon the translated package and the conveyor 48. This moistening causesthe overlapped folds of the wrapper to adhere closely to each other andto the bottom of the wrapper at the ends of the package. It alsoconditions the package so that it will not absorb moisture when thepackage is placed inside of a poultry carcass.

The moistened packages P are carried into the rolling hood 541positioned over the conveyor 48. The top wall 55 of the hood supports alongitudinally arranged series of depending bolts 56 which are securedat their lower ends to a relatively stilf but yieldably exible material57 such as a section of the conveyor belting 48. The top wall 55 isinclined longitudinally so the material 57 is inclined in rearwardlyconverging relation to the conveyor 48 and forms a roll forming stop.Springs 58 yieldably bias the front end of the flexible stop downwardlyand the remainder of the stop is weight biased downwardly.

As shown in FIG. 4, the top of each package P of articles strikes theunder side of the stop 57 while being advanced to the left by theconveyor 48. The roughened face of the conveyor 48 and the moistenedcondition of the package P causes the bottom of the package to continuein a rolling motion under the stop 57. The initially leading end 581 ofthe package is pulled up and rolled over the top of the package whilethe trailing end 59 continues longitudinally and is rolled under the nowrolling package. The ends 581 and 59 are thus rolled in rolling trailingfashion around the rolled package and the moistened condition of thewrapper causes the ends 581 and 59 to adhere to the package withsuicient force to permit the packages to be handled.

The term belts has been used in describing certain driving means andconnections but it should be understood that chain drives are commonlyused as avoiding slippage.

As stated, we have illustrated our invention in an embodiment adaptedfor the wrapping of giblets and which greatly expedites the packaging ofgiblets, and they are packaged so that they do not absorb moisture fromthe carcass into which they are inserted. It is desired to point out,however, that our invention is readily adapted to the packaging ofvarious products. We have not illustrated or described such embodimentsor adaptations as it is believed that the disclosure made will enablethose skilled in the art to adapt or embody our invention for theparticular purpose or packaging of particular objects as desired.
